Blood Drinker (Dhampir)

Benefit: Choose one humanoid subtype, such as “goblinoid” (this subtype cannot be “dhampir”). You have acquired a taste for the blood of creatures with this subtype. Whenever you drink fresh blood from such a creature, you gain 5 temporary hit points and a +1 bonus on checks and saves based on Constitution. The effects last 1 hour. If you feed multiple times, you continue to gain hit points to a maximum of 5 temporary hit points for every three Hit Dice you have, but the +1 bonus on Constitution-based skill checks and saving throws does not stack.

Normally, you can only drink blood from an opponent who is helpless, grappled, paralyzed, pinned, unconscious, or similarly disabled. If you have a bite attack, you can drink blood automatically as part of your bite attack; otherwise, you must first cut your target by dealing 1 hit point of damage with a slashing or piercing weapon (though you may feed upon a creature with severe wounds or a bleed effect without cutting it first). Once you cut the target, you can drink from its wound as a standard action. Drinking blood deals 2 points of Constitution damage to the creature you feed upon. The blood must come from a living creature of the specified humanoid subtype. It cannot come from a dead or summoned creature. Feeding on unwilling intelligent creatures is an evil act.
